Hard reset was done without any change. I was checking fuses because my power pasenger seat stoped working. The pump never produces fuel pressure until I Crank the starter for a few seconds. I believe it is supposed to as mentioned above as soon as you start the ignition without pressing the brake to make it crank. Seems like there is something electrically wrong. Pump has plent of pressure when it runs. I'd like to hot wire the pump to see if the car keeps running or see if the issue is cutting out the ignition as well. Not sure if that is doable however.

Also still see the orange triangle on the dash. Tried instructions to reset inertia switch but not sure it did anything. Instructions say start with convenience mode then swither on ignition. My puch to start is either off or ignition is on unless I am missing something. I actually can't even tell where the inertia switch is?

Im generally pretty self sufficient figureing things out but this is driving me crazy!

I don't think this is a coincidence. Retrace what you did in the fuse compartment and see if anything is amiss.

 

Convenience mode: Say the car is locked. You walk up, unlock/open a door. Inside, the displays turn on. The car is now in convenience mode. It's roughly the equivalent of position 1 on an ignition key switch. Then you press the start/stop button (without pressing the brake); all the warning indicators come on, car is now in position 2 - ignition on. Press brake and press start/stop; car cranks - position 3 (until the engine starts).

When the engine's running and you press start/stop and the engine stops, it does not go back to convenience mode, it turns right off - position 0 on a keyed ignition. Pressing start again at this point restores convenience mode.

You know you're in convenience mode because the displays are on but you're not seeing all the warning lights.

 

Looking for this post to reread but the link does not take me to a post...?

 

sorry it's post 14.

You gave me some good info in that post that has lead me to check out a few more things.The inerta switch is actually the REstraints control module from what I can see. That orange triangle seems to be telling me it is tripped but the reset proceedure is not working for me. Not sure thats the issue but that orange triangle on the dash was not there before it wouldnt run...

Still struggling...

 

Any other thoughts from anyone? I think she is going to be flat bedded to the deal this week...

I hate that I can't figure ot out....

 

I'm really sorry you haven't been able to fix this. It must be so depressing. If a battery-disconnect reset was been done, all fuses have been double-checked, and the car has been read for codes with none revealed then I for one have nothing more to suggest. Fuel pump/pressure seemed to be something to do with it but that may have been a red herring.

 

I do get one reoccuring code after resets and erasing cades... U0151-00 and U0151-31 Lost communications with restraints module...
I believe it could be related. The module has the ability to disrupt the fuel pump control module. It is what is now the inertia switch so to speak.

 

That HAS to be diagnostically significant.

 

I sure hope the dealer can help!

Spoke with a non-dealer repair center today anmd was advised that as these cars age some of the memory chips in the computers fail causing all sorts of issues. Never beeb told that before but it could be a truth, not sure.

He is over a month out so its gpoing to the nearest dealership this week unless I can think of something else to try before I can get it flat-bedded.

 

Could you hot-wire the fuel pump? This, assuming the engine then ran, would rule out other causes of the stall. In theory it might even save the cost of the flat-bed of the car becomes mobile.

I guess bad RAM in a module could indeed be a problem. Like you I've never heard of it before though.

 

Realistically no, don't hot wire.

 

This happend to me one time with my 07 while running errands. I suspected the securtiy system as the culprit. What I did to overcome the issue was to open doors, hood, trunk then close all, lock via key fob, unlock with key fob. Re-enter, start. It worked, which I why I beleived this issue was tied to ant-theft.

 

Thank you for your thoughts...

 

I just had a similar thing happen to me out shopping - car was warmed up after running around town. Came out of the store - started car, fired up and immediately shutdown - check engine light on. Tried starting it again same thing. Started it again and it started and ran fine - check engine light off. Got home, left it running and got the code reader - no stored codes. Turned it off and restarted two times with no issue. I dunno what happened here.Gonna have to carry code reader with me so if it happens again I can try an read the code related to the check engine light.

 

Was it a warm day? If so, and you’ve probably got winter blend gas now, it was probably vapor lock.
Always happens to me in the spring. Car is warm from driving, stop at a store for maybe half an hour, car starts but won’t idle, and dies.
Only way to keep it running on a restart is to push the gas pedal down, and give it lots of gas. The baby will roar, and you’ll get lots of looks from the folks in the parking lot! But keep giving it gas for a few seconds, until it will idle normally when you let off the gas.
It’s that winter blend and warm weather that just don’t get along.
Short periods of engine off, restart ok. Long periods of off, so everything cools down, will also start ok. But that 1/2 to 1 hour of off time, is troublesome.

 

Only about 10 C out, sunny with cloud. I did give it lots of gas on the third try. I was really close to the curb and the front sensor blared out when starting the car, not sure if the thought I was in for a front end crash (it's that's possible for the park system to shut the engine down).

I'm not sure when we get the winter gas in lower BC.

 

Its been down for over 2 weeks and Ive tried on cold and warm days....
